Description

Mapei Adesilex G19 2K Adhesive
– 5kg Tub

Mapei Adesilex G19 Adhesive is an extremely strong, tough, elastic,
adhesive for general purpose use, particularly for non-absorbent substrates or
moisture-sensitive substrates (wood, metal, ceramic, stone, resin, PVC, rubber,
etc.). Mapei Adesilex G19 Adhesive is a two-component, epoxy-polyurethane adhesive
designed for use with resilient and textile flooring.

WHERE TO USE

Extremely strong, tough, elastic, adhesive for general purpose use,
particularly suitable for non-absorbent substrates or moisture-sensitive substrates
(wood, metal, ceramic, stone, resin, PVC, rubber, etc.).
For use on floor in interior and exterior applications.
Specifically developed for the installation of rubber athletic tracks.
Also suitable as universal adhesive for rubber, PVC and all common
resilient and textile floor covering types, especially in the event of extreme
temperatures due to solar radiation, intense mechanical stress by lift truck,
forklift, etc. or frequent washing (in particular when the floor coverings are not
welded or sealed).

APPLICATION EXAMPLES

Use Adesilex G19 for bonding:

rubber athletic tracks and multisport flooring on asphalt;
recycled rubber shock-absorbent flooring on asphalt in playgrounds.
resilient flooring for indoor sports flooring, also onto waterproofing
fiberglass underlays such as Mapelay;
homogeneous and heterogeneous PVC, sheets and tiles;
CV floor coverings;
LVT;
semi-flexible quartz vinyl floor tiles (VIC);
textile floor coverings with all common backings (latex-primed, PVC and
polyurethane foam, natural jute and Action-Bac® backed carpets etc.);
needlepunch woven flooring also in latex;
flocked textile flooring;
linoleum with all kind of backings;
polyolefin-based and chlorine-free floor coverings;
PUR floor coverings.

TECHNICAL CHARACTERISTICS

Adesilex C19 is a two-component adhesive made from an epoxy-
polyurethane polymer, component A, and a special hardener, component B.
When the two components are mixed together, they form an even coloured
paste which is easy to apply with a suitable notched trowel.
After setting (around 24 hours), which takes place by means of a
chemical reaction without any shrinking, Adesilex G19 becomes tough and resistant
to moisture, water, heat and atmospheric agents, and adheres extremely well to
almost all materials normally used in the building industry.

RECOMMENDATIONS

Install in recommended temperatures, normally between +10°C and +30°C,
in order to maintain workability and setting times.
Do not install on substrates not protected from rising damp.
Do not install flooring on not completely set or wet concrete (residual
moisture content must be maximum 3.0%).
Do not install flooring on fresh asphalt (wait at least 20 days).
Do not install flooring on bituminous surfaces which might bleed oils.
Do not use on curved surfaces or steps if it is not possible to hold
the flooring in perfect adherence against the substrate until the adhesive has set.
When installing thin flooring where the ribs of adhesive may shadow
through, use Adesilex G20 or Adesilex G20 Fast.
When a rapid adhesive with faster setting is needed, use Adesilex G19
Fast.

APPLICATION PROCEDURE

Preparation of the substrate

Substrates must be dry, level, sound, mechanically strong, free of
dust, loose particles, cracks, paints, wax, oil, rust, traces of gypsum or other
products that can interfere with bonding.
The regulations of each country must be strictly followed.
Commonly, the moisture content must be as follows: max. 2%-2,5% for
cementitious substrates, max. 0,5% for gypsum or anhydrite-based substrates.
It is essential to make sure there is no rising damp present. Un-bonded
screeds laid over light-weight concrete or over insulation and screeds laid
directly onto earth must be separated by a vapour barrier to prevent rising damp.
To repair cracks in the substrate, consolidate and waterproof screeds,
form new fast-drying screeds and level uneven substrates, please refer to the
relevant MAPEI documentation or contact Mapei Technical Services.
External cement based surfaces may be levelled off with Planicrete
mixed with cement and sand (with suitable particle size) or with Adesilex P4.
Use Adesilex G19, Adesilex G19 Fast, Adesilex G20 or Adesilex G20 Fast
(eventually mixed with suitable quartz or crumbled rubber) for repairing or
smoothing asphalt surfaces. In these cases install the flooring with Adesilex
G19 as soon as the smoothing layer is set enough to take light foot traffic.

Acclimatisation

Before starting the installation, make sure that the floor covering and
substrate are acclimatised to the recommended temperatures and R.H.

Mixing the adhesive

The two components of Adesilex G19 are supplied in pre-measured
proportions:

component A: 9.4 parts by weight;
component B: 0.6 parts by weight.

Blend the two components together with a mechanical mixer until an even
paste is obtained.
Setting times and pot life depend on the ambient temperature (see
below).
Setting times are much longer if the temperature is lower than +10°C.

Note: the resin (component A)/hardener (component B) ratio must be strictly
adhered to. Any variation in dosage will compromise the setting of the product.

Spreading the adhesive

The choice of trowel depends on the type of flooring to be installed
and on the substrate:

for smooth backings and smooth substrates use MAPEI No. 1 or TKB A1, A2
trowels;
for textured and impervious backings and substrates use MAPEI No. 2, 3,
4 or TKB B1, B2, C1 trowels.

Only apply as much adhesive as can be covered within the open time (60
minutes) and with good transfer to the backing of the covering.

Installing the flooring

Follow the manufacturer’s instructions for laying technique.
Lay in covering with short waiting time into the still wet adhesive
bed: the adhesive ridge has to be impressed.
Take care to avoid air pockets and carefully rub the floor covering
down to ensure good adhesive transfer to the backing.
Avoid excessive stress at the seams.
After installing the floor covering, it is always necessary to
carefully
roll it down again or to firmly rub it down.
If the flooring is not perfectly flat, put weights (such as bags of
sand or similar) on the uneven areas, and on the joints and roll ends until the
Adesilex G19 has hardened (12-24 hours).
Extra care must be taken when installing external flooring if there are
high temperatures or high variations in temperature (install flooring during the
cooler hours of the day).
Flooring bonded with Adesilex G19 is ready for light foot traffic after
around 12-24 hours, while the adhesive sets completely after around 72 hours at
+23°C.

The setting time of Adesilex G19 at different temperatures is the following:

CONSUMPTION

Consumption varies according to the flatness of the substrate and the
type of backing on the flooring material (and, therefore, the type of trowel used):
1. trowel No. 1 or TKB
2. A1/A2: 350-450 g/m²;
3. trowel No. 2 or TKB B1; B2: 450-550 g/m²;
4. trowel No. 3 or TKB C1: 550-750 g/m²;
5. trowel No. 4: 750-1000 g/m².

CLEANING

Adesilex G19 may be removed from flooring, tools, clothing etc. with
alcohol before it hardens.
Once hardened, it must be removed mechanically or with Pulicol 2000.

COLOUR

Adesilex G19 is available in the following colours: beige, red, green
and black.
Special colours available uponrequest (min. 600 kg).

PACKAGING
